I’m trying to get my spring application working, following a guy who posted an example with earlier spring version. I’ve been having many problems with his example so I’m not posting a link so as not to lead anyone else astray. Fighting through issues, I was able to get to the point where things are working. Somewhat. I have not been able to figure out the following two things:

  1. $(message) isn’t printing the message which is a bean of type String.
  2. <c:out value="${message}" prints the message but only if I add <%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> to the jsp. I would assume that adding jtslview class to the resolver would be enough. It’s not. What’s wrong here?

setup

  Eclipse IDE for Java EE Developers    1.4.1.20110909-1818 epp.package.jee 
  Tomcat 7
  Spring 3 distribution (all jars in /lib)
  lib/jstl-1.2.jar

jsp in question

<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Message View</title> 
</head>
<body>
    $(message)
    <br>
    message=$(message);
    <br>
    message=<c:out value="${message}" />
</body>
</html>

this prints the following. The message “bean” is clearly passed to the page.

$(message) 
message=$(message); 
message=Hello World from Spring MVC!

    The syntax for the JSP expression language is ${some expression}. Not $(some expression).

    Each time you use a JSP tag, its tag library must be declared in the JSP. The fact that you configure Spring to use a JstlView has nothing todo with the possibility of using the <c> tags. It just configures Spring to perform appropriate actions before dispatching to the view.

    <c:out> should always be used to render a string, unless you’re absolutely sure that the string doesn’t contain any character that must be HTML-escaped. Not using it opens the door to attacks where a user could submit a text containing </html> or a piece of javascript code that would compromise your web site.

    Read the official tutorial about servlets and JSPs: http://docs.oracle.com/javaee/5/tutorial/doc/bnadp.html
